DEVICE REGISTER ADDRESSING

ADDRESS XX000 — STATUS REGISTER
(STATR_S)
the various configuration register contents without disrupting
the device operation or the register contents. The register bits
D[4:0] determine the content of the first sixteen bits of SO
data. In addition to the device status, this feature provides the
ability to read the content of the PWMR_s, CONFR0_s,
CONFR1_s, OCR_s, GCR and CALR registers (Refer to the
section entitled
Return Data) on page

of corresponding output through the SPI. Each output “s” is
independently selected for configuration based on the state
of the D14 : D13 bits
